Runtime state-management services are a collection of interfaces defining the contract that PingFederate uses to manage session states for each service.
The <pf_install>/pingfederate/server/default/conf/META-INF/hivemodule.xml file specifies the implementation of each service. You only need to modify this file if you want to customize the way services are handled in a cluster. You must manually replicate your changes in each cluster node.
Configuration files for the services are located in the <pf_install>/pingfederate/server/default/conf directory.
